First of all, cerebrovascular is a general and colloquial term that should refer to the blood supply arteries to the brain. Whether a patient should be stented (stenting of stented vessels) or not, cannot be simply defined by any rules and regulations, even the latest international guidelines. Each patient is unique. The indications for the treatment of stenosis of the cerebral blood supply arteries are mainly considered in the following aspects: 1. whether there are obvious symptoms, whether they can be controlled by medication, or whether they can be controlled by adherence to medication. The symptoms here are not dizziness or scalp pain, but mainly cerebral infarction or transient ischemic attack associated with the stenosis. The more severe the stenosis and the nature of the plaque, or the more unstable the nature of the plaque (embolus can be dislodged at any time and cause embolism), the more treatment is recommended. 3.Whether the symptoms are related to the stenotic vessel, sometimes the brain infarction is caused by the small intracranial penetrating vessels, not the larger vessels. 4. Assessment of the ischemic condition of the brain tissue, whether there is a hemodynamic deficit. Because sometimes although the vessel is narrowed, but the other vessels form a good and sufficient compensation, then the risk-benefit ratio of surgery is high. In conclusion, try to avoid surgery for diseases that can be controlled with medications, and try to avoid medications for diseases that can be controlled without medications. Although we are physicians, these recommendations must be made known to our patients. Unfortunately, patients are often criticized in outpatient clinics for not prescribing Chinese medicine to invigorate the blood.
